I was speccing to the 10-15 kwh range. Maybe you can get it for cheaper, but with the use case he described you're talking about a substantial continuous rated power and surge power. How many amps can your $10,000 50 kwh battery push? Also I'm including installation, warranty, etc. It would honestly probably be more than that because he'd likely need a more expensive inverter or 2 inverters to deal with that kind of load (I doubt his AC unit and dryer are DC).

His AC unit and dryer may actually be DC, just internally. Modern AC compressor motors are now moving to inverter drive, so incoming alternating current gets turned into DC for the inverter, washers/driers do something similar for the motor. Heating elements are just a resistor, so could run from DC. If I were putting together a system for myself those are the things I would consider, and find ways not to duplicate power inverters throughout the system.
